MRI Hardware Design
You enjoy engineering challenges and working in interdisciplinary teams? Then this practical lab work (“Fachpraktikum”) is just the right thing for you!
You will work in several complementary teams towards the common goal of building and commissioning a fully functional MRI scanner.
The various subtasks offer each student the opportunity to use his/her strengths profitably for the team. Be it in the field of FEM simulation for the design of the required permanent magnet and the gradient system, for the high voltage electronics of the gradient amplifier or for the design of the RF sensor and the RF electronics. There is something for everyone in this specialized internship.
In this practical lab work (“Fachpraktikum”), participants will design a fully functional magnetic resonance imaging (MRI) scanner in benchtop format, which will be able to take real MR images at the end of the semester. The students are divided into different subgroups, each of which is working on one aspect of the scanner design. One group is working on the construction of the permanent magnet, which generates the required highly homogeneous magnetic field. This team will also evaluate strategies for temperature compensation of the magnetic field. Another group designs and implements the fast switching gradient system, which allows the local coding of the MRI image. Finally, two more groups are engaged in the design of the MR sensor and the high-frequency electronics as well as the required imaging software. Close cooperation of all groups is essential for the joint success of the whole project.
Design of a fully functional benchtop MRI scanner including the design of all relevant components of an MRI scanner:
- gradient system
- transmit/receive coil(s)
- RF electronics
- imaging software
- fun and joint success in interdisciplinary teams
